Build Status

A python package providing an easy way to explicitly import Jupyter Notebooks files (.ipynb) the same way you would import regular .py files.


You can install ipynb with:

pip install ipynb

Importing a notebook

Full import

You can do a 'full' import - this has the same semantics of importing a .py file. All the code in the .ipynb file is executed, and classes/functions/variables in the top level are available for use.

If you have a notebook file named server.ipynb, you can import it via:

import ipynb.fs.full.server

You can use the from ... import .. too.

from ipynb.fs.full.server import X, Y, X

Definitions only import

Sometimes your notebook has been used as a way to run an analysis or other computation, and you only want to import the functions / classes defined in it - and not the extra statements you have in there. This can be accomplished via ipynb.fs.defs.

If you have a notebook file named server.ipynb, and do:

import ipynb.fs.defs.server

It'll only execute and make available the following parts of the code in server.ipynb:

  • class definitions
  • def function definitions
  • import statements
  • Assignment statements where the variables being assigned to are ALL_CAPS. These are assumed to be constants.

This skips most computational work and brings in your definitions only, making it easy to reuse functions / classes across similar analyses.

Relative Imports

You can also easily do relative imports, both for full notebooks or for definitions only. This works inside notebooks too.

If you have a notebook called notebook1.ipynb in the same dir as your current notebook, you can import it with:

import ipynb.fs  # Boilerplate required

# Do a full import
from .full.notebook1 import foo

# Do a definitions-only import
from .defs.notebook1 import bar

This works transitively nicely - other code can import your notebook that's using relative imports and it'll all work well.
